Finlandic if it’s pc there will be a discord icon and will have “log in” next to it. It’ll be to the left of the tag, code and name boxes. Click that and it’ll open a new tab and take u to a login page. Login with your email and password for discord and then it will say “you can close this tab now” or something along those lines. Go back to the senpa tab and you should be logged in. If it’s mobile there currently isn’t a log in system yet but @Mistik will add it in the new app.
